TECHNICAL FIELD

This invention relates to the field of mobile audio/video capture, analysis, processing and compiling of data including audio files and video files with a mobile device.

BACKGROUND

The problem with current technology is that current mobile devices have limited capabilities of capturing quality audio primarily because the quality of microphone and the microphones proximity to the subject.

Other systems are limited in several aspects specific to audio. Smart devices, such as smart phones have increasing capabilities with several application including camera and video camera function. The current design of a smart phone in one embodiment, the iPhone®, does not enable ‘remote’ audio capture as the audio microphone input is located on the phone, or the device.

FIG. 1 illustrates an apparatus for remote capture of audio in a handheld device, in accordance with some embodiments. Device 100 can be used to capture and record audio input.

AlignSync is a tool within the method of the invention (the AlignSync tool is also referred to herein as an application, module, or algorithm). The AlignSync application, in one embodiment addresses latency issues between the audio and video data.

In some embodiments, the AlignSync tool is implemented with one or more handheld consumer devices.

In another embodiment, the device is another iPhone®.

FIG. 2A illustrates an apparatus for remote capture of audio in a handheld device, in accordance with some embodiments. In some embodiments, the device 200 is an electronic device with audio capabilities.

In another embodiment, the device is a specifically designed apparatus for capturing audio input.

In another embodiment, the above apparatus, captures, stores, and transmits audio data to a separate device using wireless technology. FIG. 2B illustrates an apparatus 201. The apparatus 201 includes an elongated housing structure 210 of sufficient length to fit in the palm of a human hand, the elongated housing structure with two ends; a microphone 220 operable to capture audio data located on one of the two ends of the elongated housing structure; an antenna 230 within the housing structure, operable to transmit wirelessly the captured audio data to other devices; a clip 240 attached to the elongated housing structure, operable to attach the housing structure to human clothing; a processor 250; a first memory 255 coupled to the processor; instructions 256 stored on the first memory, operable to cause the processor to execute a wireless protocol; a wireless application programming interface (API) 252 executable by the processor to send and receive data; a wireless chip 260 coupled to the processor 250, the wireless chip operable to send and receive wireless signals; a battery 270, which supplies power to the microphone, the antenna, the processor, the first memory, and the wireless chip; wherein the apparatus can be worn and used by a human as a lavaliere microphone, and wherein the apparatus can be used as a hand-held microphone. In some embodiments, the apparatus 201 further includes a second memory 258, coupled to the processor 250, operable to store streams of audio data captured by the microphone 220. In some embodiments, the housing structure 210 is attachable to a stand 280 via a tripod socket 285, thereby permitting hands-free use.

A method in which audio is captured on a device, transmitted via wireless technology, to a second device.

A method in which a device capable of collecting audio input wirelessly from a second device, wherein there first device is also capable of video input, wherein the method includes a software application that uses the AlignSync module on the audio and the video.

In one embodiment the AlignSync module is pre-programmed to automate the synchronization of the audio with the video.

In one embodiment, the AlignSync module has user defined parameters.

In one embodiment, the second device is a smart phone.
